And it has left people online scratching their heads as they try to spot the dog, who has managed to blend into his surroundings.

The picture, which was posted on Facebook group Surrey Dog Owners over the weekend by dog owner Karen Fornos Klein of her pet Ambar, has been viewed hundreds of times by people desperately trying to locate him.

If you look closely, you might be able to spot the dog’s head poking out from its background.

And for those who are able to spot the dog, once you see it, you can’t help but wonder why you didn’t see it in the first place.
